Adding additional media format support to QuickTime

Use codec components to extend QuickTime to import or play a variety of additional media formats (such as .wmv, .divx, .mpeg, .mxf).

You can extend QuickTime to import or play other popular and specialized media formats using codec components. The table below lists common Apple and third-party codec components and the filename extensions they support. Note: Check the codec component vendor's website for specific QuickTime and OS version requirements. Some codec components may require purchase.

To determine which component will most likely work for you:

  1. Identify the filename extension of your media file:
    1. If you haven't already, download the file to your desktop or other folder.
    2. In Finder, select the file and choose File, then Get Info.
    3. In the info panel, click the triangle next to Name & Extensions to expand that section and see the full filename with extension. If the filename is long, click in the filename box and scroll to the right to display the extension.
  2. Match the filename extension to those in the table below and go to the linked website for more information.

Note: Third-party video cameras and capture hardware may use codecs components that are included with the software that comes with the device. If you have issues playing media from a third-party device, make sure the software that accompanied the device is installed on your computer.

Some older codec components may require that "Open in 32-bit mode" be enabled in QuickTime player. See this article for more information.
